Interventions designed to reduce alcohol use among fraternity members are no more effective than no intervention at all, according to an analysis of 25 years of research involving more than 6,000 university students.
“Current intervention methods appear to have limited effectiveness in reducing alcohol consumption and alcohol-related problems among fraternity and possibly sorority members,” said lead researcher Lori Scott-Sheldon, Ph.D., of the Miriam Hospital and Brown University.
“Stronger interventions may need to be developed for student members of Greek letter organizations.”
The researchers conducted a meta-analysis of 15 studies looking at 21 different interventions involving 6,026 students who were members of fraternities and sororities. About 18 percent of the students were female.
The study’s findings revealed no significant difference between students who received an intervention and those who did not for alcohol consumption per week or month, frequency of heavy drinking, frequency of drinking days, or alcohol-related problems.
In fact, in some cases, alcohol consumption increased after an intervention, according to the study’s findings.
Alcohol use is common among U.S. college students, but especially among those in fraternities and sororities, according to the study.
It also notes that members of the Greek system consume higher quantities of alcohol, report more frequent drinking, and experience more alcohol-related consequences compared to students outside the Greek system.
The researchers said they were surprised by the findings.
“We expected that providing Greek members with a thoughtfully designed and carefully administered alcohol intervention would reduce consumption and problems relative to no intervention,” Scott-Sheldon said.
One reason for the unexpected findings could be the nature of fraternity and sorority life, according to the researchers.
Changing patterns of alcohol use by members of these organizations may be more difficult than changing them among regular university students because these students are part of an environment in which alcohol plays a central social role, she explained.
“Reducing alcohol consumption and problems among fraternity and sorority members will require a different strategy relative to their college drinking peers,” said Scott-Sheldon. “Additional research is needed to determine the best approach to reduce alcohol misuse among members of Greek letter organizations.”
It is important to note that since only 18 percent of the participants in the studies represented in the meta-analysis were women, and no single study focused exclusively on sororities, the findings may only be applicable to members of fraternities, according to Scott-Sheldon.
“Given the lack of research with sorority members, our findings may not be generalizable to all members of Greek organizations. More research is needed to determine the efficacy of alcohol interventions specifically for sorority members,” she said.
The study appears in the journal Health Psychology, which is published by the American Psychological Association.
